Federal Reserve North Garage Expansion Project

The Federal Reserve Board is letting Sossii propose the redesign of the North Parking Garage of the Martin Jr. Building. The goal of the project is to redesign, expand, and raise the underground parking garage to allow for the maximum amount of parking spaces and for taller vehicles to enter the garage. Another priority is the design of the unnamed park located on top of the parking garage. There will also be an addition of a retaining wall to the park along Virginia Avenue to reduce the pedestrian traffic on the edge of the property. Along with the redesign there will also be the inclusion of sustainable features to mitigate the leakage issue. This will include the design of a green roof and a bioswale plus research on the watershed data.

RFK Stadium Redevelopment

MASStructural is pleased to present the following proposal for the redevelopment of Robert F. Kennedy Memorial Stadium. Located on East Capitol Street in the epicenter of Southeast, DC, RFK Stadium was commissioned in 1961 and proudly served as the home to the Washington Redskins, Washington Nationals, and DC United. In September 2019, it was officially announced that the Stadium would be torn down and repurposed. MASStructural has beenretained to conduct a feasibility study and propose a conceptual master plan for the reuse of the land. Based on preliminary desktop studies of the surrounding area, the 190 acre site is positioned adjacent to the Anacostia River and collinear with the National Mall. These strategic locations governed the design of the landscape which aims to incorporate the existing natural environment with the new built environment. Water features are prominently interspersed throughout the site to integrate the waterfront with the proposed design scheme. Moreover, sustainable design strategies have been implemented including bioretention ponds and planters as well as community areas designated as greenspace.

Hurley Avenue Bridge Rehabilitation

The city of Rockville, Maryland has provided funding to its Department of Public Works for the planning, design, and reconstruction to rehabilitate the Hurley Avenue Bridge (Bridge MR-03) near the Watts Branch Parkway. Constructed in 1969, the composite bridge is a 60ft spanning steel beam superstructure supported by reinforced concrete abutments which sit on reinforced concrete caissons. The bridge permits the flow of the Watts Branch Tributary below and connects suburban Rockville to MD Route 28. The primary goals of the rehab are to increase the bridge’s current live load capacity and to satisfy the Maryland DOT inspection and AASHTO design standards.

Gaithersburg Stormwater Management

The City of Gaithersburg Public Works Department is seeking to improve and update the stormwater management practices of one of the parking lots located at their 800 Rabbitt Road, Gaithersburg, Maryland facility. The ultimate goal is to increase water quality and receive treatment credits from the state of Maryland. The new Maryland standards, referred to as the Environmental Site Design (ESD), focus on utilizing natural hydrology to collect and treat runoff. The requirements for a stormwater management system update are found in the 2010 revision of the Maryland Stormwater Design Manual (MDE). The existing conditions of the site includes 94% impervious surface and one stormwater treatment practice, a BaySaver Hydrodynamic Separator. The BaySaver provides minimal runoff treatment, only removing large sediments, failing to treat the water any further. Project deliverables for updating the stormwater management practices include the design of micro-bioretention filters and bioswale channels to be installed at the site. Both the micro-bioretention and bio-swales are more sustainable methods and will provide cleaner water than the current BaySaver.

Boys and Girls Club Storage Building

The Boys and Girls Club has come to us with a new project. They want us to build a new storage building for them that can hold their ever expanding amount of equipment. The current building that is in use is over 30 years old and has no design plans. In addition, the building cannot hold all of the equipment for the Boys and Girls Club and has a press box that is a potential hazard. The client came to us so we could build a bigger and better building for the Boys and Girls Club, since the current building has no building records we thought we would build a new one from scratch. The new building is going to be 40 x 70 feet in dimensions and it is also going to be 10 feet tall. On the far left side of the building we have decided to add in a press box so that they can still call all of the sports games. The press box is going to be a 10x10 with a stair entrance from the side. This structure is going to be made up of concrete, lumber and aluminum. The concrete is going to be used for the foundation in which this structure stands on and for the press box. The rest of the structure will be built from lumber and aluminum. There will be 2 garage doors that will be 8x8 feet. We will also have two main entrances, one from the front (facing the field) and one from the back. We are also going to build this new building in a new location so that the club can still use their existing building during the building process. The location of the new storage is going to be next to the old storage by a couple of feet, so it will not be hard to move the equipment to the new storage. We are also going to build the press box on the left side of the storage because it is closer to the center of the field.

Project for a New Gymnasium in Bowie, MD

The design team at Parker & Sons has been commissioned to design a new gymnasium with the City of Bowie, Maryland. The city currently has a gymnasium that is constantly booked for organized activities, and their hope is for this new gym to be a community-building arena for more informal play. The following report provides the constraints and considerations requested by the City of Bowie, as well as each team member’s conceptual and structural designs. The proposed budget for this facility is $4 million with a ceiling of $5.5 million. Due to this budget, the city preferred a tension-fabric or pre-engineered steel structure. The team decided against a tension-fabric building as the team members have more experience with steel design, and the client preferred it over tension-fabric.

Sligo Mill Road Stormwater Runoff

The city of Takoma Park Maryland has requested that Capital Green Consultants (CGC) make green stormwater infrastructure improvements at Poplar Mill Natural Park, a wooded area at the end of Sligo Mill road. Sligo Mill road is a dead-end street that leads to the park and the Takoma Branch. The branch is relatively small but has deep banks. Stormwater runoff has caused severe erosion of one section of the branch bank.
